In this blog series, we’ll delve into the significance of ARIA in web design, exploring real-life cases where its implementation has made a tangible difference in creating an accessible digital space.
Exploring ARIA’s Purpose
Origin of ARIA
Accessible Rich Internet Applications (ARIA) was developed by the W3C Web Accessibility Initiative in 2006 to address the limitations of traditional HTML in terms of accessibility. By providing a way for web developers and designers to make their content more accessible, ARIA has significantly contributed to improving the online experience for individuals with disabilities. It offers a set of tools and techniques that enable assistive technologies, such as screen readers, to convey complex information more effectively.
ARIA’s introduction marked a significant milestone in web accessibility. The WebAim survey revealed that home pages with ARIA present averaged 41% more detected errors than those without it. This statistic underscores the importance of understanding not only how to implement ARIA but also how it should be used correctly to achieve its intended purpose.
ARIA for Web Accessibility
One key aspect of ARIA is its ability to enhance the accessibility of web applications and dynamic content. Through various attributes and roles, it provides additional information about elements on a webpage, making them easier for assistive technologies to interpret accurately. For instance, when navigating through a website using a screen reader, users can encounter interactive elements like buttons or menus labeled clearly thanks to ARIA attributes.
Moreover, this technology caters specifically to individuals who rely on assistive technologies by enabling them to interact seamlessly with different types of content found on websites. For example, someone who uses voice commands due to motor impairments can benefit from well-implemented aria-labels that describe images or controls within an interface.

Accessible Rich Internet Applications (ARIA) consist of roles, states, and properties. These components are vital for enhancing the accessibility of web content. The roles define the type of element or widget present on a webpage, such as buttons, menus, sliders, and more. Meanwhile, states describe the current condition or status of an element, like whether it’s expanded or collapsed.
Using an h1 element in HTML is preferred over applying the heading role to a div element. This ensures semantic correctness and aids assistive technologies in understanding the structure of the content.
Properties of ARIA
In addition to roles and states, ARIA also includes properties that provide supplementary information about elements beyond their role and state. These properties can modify default behavior or add custom functionality to elements on a webpage. Some examples of properties include aria-label, which provides a text label for an element when its visual label is not present; aria-described by, used to point to another element that contains a description; and aria-hidden, which indicates whether an element is visible or hidden from view but still accessible via assistive technology.
The accessibility tree serves as a hierarchical representation of accessible elements on a webpage. It plays a crucial role in enabling assistive technologies such as screen readers to navigate through web content effectively by providing them with structured information about the page’s elements and their interactions.
Proper utilization of ARIA ensures that the accessibility tree accurately reflects both the structure and functionality of the webpage being accessed by individuals with disabilities. By incorporating appropriate roles, states, and properties into web development practices, developers can significantly enhance how users interact with their websites using assistive technologies.
Integrating ARIA with HTML
Dynamic Content Updates
ARIA plays a crucial role in ensuring that users of assistive technologies are informed about changes. Live regions, which can be designated within the HTML code, allow developers to notify assistive technologies about updates without requiring any user interaction. For example, if there’s a section on a website that displays live sports scores or stock market updates, incorporating ARIA live regions will ensure that individuals using screen readers or other assistive devices receive immediate notifications when these values change.
Developers should prioritize making sure that dynamic content updates are effectively communicated to users with disabilities. This means providing clear and accurate descriptions of the changes occurring on the webpage. By doing so, individuals who rely on assistive technologies can stay informed and engaged with the latest information without encountering barriers due to their disability.
It’s essential for developers to thoroughly test how dynamic content is relayed through different types of assistive technologies. This ensures compatibility across various platforms and devices commonly used by individuals with disabilities.
ARIA also empowers developers to create non-semantic controls while maintaining accessibility for users of assistive technologies. These non-semantic controls provide custom functionality without sacrificing accessibility features. An example could be a customized dropdown menu or interactive widget designed specifically for a website’s unique needs.
However, it’s important for developers to exercise caution when utilizing ARIA for non-semantic controls and instead prioritize native HTML elements whenever possible. While ARIA offers valuable tools for enhancing accessibility in web development, overusing non-semantic controls created through ARIA may lead to unnecessary complexity in the codebase.
By prioritizing native HTML elements over non-semantic controls whenever feasible, developers can leverage existing structural components that inherently possess built-in accessibility features compatible with various assistive technologies.
Native HTML Elements vs Custom Controls
Native HTML elements offer several advantages over custom controls created using ARIA attributes:
- Native elements are more familiar and predictable for users.
- They often come pre-equipped with standard keyboard interactions.
- Native elements typically have better support across different browsers and devices compared to custom-built solutions reliant on specific implementations of ARIA attributes.
On the other hand, custom controls developed using ARIA attributes may be beneficial under certain circumstances:
- They allow flexibility in creating highly specialized interfaces tailored specifically for unique website requirements.
- Custom-built solutions enable fine-tuning details such as visual appearance and behavior beyond what native elements offer.
Despite these benefits, it’s crucial not to overlook potential drawbacks associated with excessive reliance on custom-built solutions using ARIA attributes:
- Overcomplication: Using numerous customized control mechanisms via ARIA may lead to unnecessarily complex code structures.
- Compatibility Issues: Depending heavily on non-native components might result in compatibility challenges across various platforms and devices.
Utilizing ARIA Roles
Role of ARIA in Accessibility
ARIA, which stands for Accessible Rich Internet Applications, plays a crucial role in making web content accessible to individuals with disabilities. By assigning specific roles to elements within a webpage, ARIA bridges the gap between complex web applications and assistive technologies such as screen readers or voice recognition software. For instance, when a website utilizes ARIA roles effectively, it allows users with visual impairments to navigate through the content more easily.
Proper implementation of ARIA can significantly improve the user experience for people with disabilities by providing them with meaningful information about various parts of a webpage. This ensures that they can interact with different components on the site without facing barriers due to their disability. For example, if an online form is labeled using appropriate ARIA attributes, individuals who use screen readers will receive accurate descriptions of each form field and be able to complete the form independently.
